Description

A kind of knight's car sample vehicle frame rear section structure processing method
Technical field
The present invention relates to frame of motorcycle manufacture field, add in particular to a kind of knight's car sample vehicle frame rear section structure Work method.
Background technology
In motorcycle, riding-type motorcycle, as the vehicle of a classics, has power big, and it is excellent that performance of driving over a long distance is good etc. Point, firmly gets liking of consumer.Motorcycle is in R&D process simultaneously, generally requires first R & D design and goes out sample product, carries out Testing inspection, to ensure the dependable with function of final finished.
In the trendy riding-type motorcycle that a model is LF-150-10b, its main body of vehicle frame structure includes head tube, car On rear side of head tube pipe, lower end is fixed and is connected the front inclined tube extended to the back lower place, on rear side of head tube before the fixing connection backward in upper end main-beam pipe End, the main-beam pipe second half section bends downwards along medium position and connects electromotor in end, rear end hangs installing rack, on rear side of head tube Medium position is fixedly connected with head tube connecting plate, head tube connecting plate upper end and main-beam pipe underside of forward face and fixes, head tube Connecting plate lower end and front inclined tube front portion are fixed, after described front inclined tube in the middle part of upper side medium position and main-beam pipe under front, bending place The most oblique between surface it is fixedly connected with a connecting tube；In the middle part of described main-beam pipe, both sides, back upper place, bending place each connect setting Having a upper pipe extended back, described electromotor hangs that both sides on installing rack are the most extended two down tubes, and two After root down tube, upper end is fixedly connected on two upper pipe second half section lower surfaces, and two upper pipe latter ends extend obliquely out the most rearwardly and upwardly and set Put.
The trendy riding-type motorcycle frame of complete LF-150-10b, on the basis of above-mentioned main body of vehicle frame structure, also needs Will be at one direction limited block of head tube upper end installed in front, before front inclined tube lower end extends transversely through two electromotors of fixing connection Suspended axle, extends transversely through in head tube connecting plate centre position and fixes a fuel tank installation axle, in the left and right of front inclined tube first half section Both sides also need fixing welding one for installing the radiator journal stirrup of radiator, at left side and the rear side of main-beam pipe rear section upper end Also need respectively to be welded and fixed one for the storage battery journal stirrup installing storage battery, on main-beam pipe rear section top and two between pipe front end Also needing to be welded and fixed a front boss, described electromotor hangs installing rack front side portion upper-lower position and also needs to extend transversely through respectively Descending suspended axle after suspended axle and electromotor on after arranging electromotor, electromotor hangs the forward position of installing rack right side central and also needs weldering Connecing and fix a side cover lock journal stirrup, electromotor hangs also to need to extend transversely through in the middle part of installing rack and arranges bottom fork axis, bottom fork axis and down tube Front end offsets setting；In the middle part of two down tubes, outside also needs to be welded and fixed a side cover down journal, between two upper pipe forward positions Also transverse lap is fixed with one piece of air filter bracket；The down tube upper end on the left side is also welded with an electrical part journal stirrup, upper pipe After rear portion and down tube link position front proximity are welded with downwards journal stirrup after a side cover, down tube rear side and upper pipe Reinforcing plate after being also welded with one piece between Xia Ce, described rear reinforcing plate lateral rear is welded with downwards one piece of medicated cushion Lock support, two upper pipe tail ends overlap laterally over and are fixed with a fast seat cushion after-poppet, and below upper pipe tail end, transverse weld is fixed There is one piece of tail-hood support.
Above-mentioned body frame structure for automotive, when motorcycle research and development sample produces, it is common that division of labor step is sequentially completed in main body of vehicle frame respectively Component and being welded and fixed one by one of each Accessory Members on it；Again each component of main body of vehicle frame is welded and fixed successively.So, exist Operation is various, operation complexity, the defect of high cost.Usually need some Local Members are installed especially because sample produces Position and setting angle are adjusted, and each adjustment all uses the weld jig of fixed structure to realize welding, greatly increases Cost, constrains the expansion of sample research and development.Wherein during vehicle frame rear section welding processing, the problems referred to above defect is the most prominent Go out.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved is: how to provide one can letter Chemical industry sequence so that it is simple to operate, with low cost, and can conveniently manufacture experimently knight's car sample vehicle frame rear portion of adjustment further Segment structure processing method.
In order to solve above-mentioned technical problem, present invention employs following technical scheme: scheme relates to orientation when describing, Install rear state with it and describe benchmark for orientation.
A kind of knight's car sample vehicle frame rear section structure processing method, it is characterised in that first use weld jig to complete right After down tube rear section, electrical part journal stirrup, side cover, journal stirrup, upper pipe end segment, rear reinforcing plate, cushion lock support and tail-hood support determines Position；Use welding gun to complete being welded and fixed of above-mentioned component again, wherein realize to upper pipe end segment location structure include for The upper pipe end segment hold-down mechanism that in realization, pipe end segment compresses, upper pipe end segment hold-down mechanism can horizontally rotate setting and complete After becoming above-mentioned welding, the horizontal rotation of upper pipe end segment hold-down mechanism is outwards avoided interference with, then completes the installation of seat cushion after-poppet Location, then realize being welded and fixed of seat cushion after-poppet.
So, this method can be greatly enhanced working (machining) efficiency, can also avoid interference with simultaneously, and it is right to realize conveniently and efficiently The clamping welding of seat cushion after-poppet, drastically increases vehicle frame integral solder efficiency.
The weld jig wherein used, is all disposed with some peaces according to constant spacing array including upper surface and week side surface The three-dimensional mounting platform in dress hole, also includes the down tube rear section positioning component for realizing down tube rear section location, for realizing The electrical part journal stirrup positioning component of electrical part journal stirrup location, for realizing after side cover after the side cover of journal stirrup and rear reinforcing plate location Ear and rear reinforcing plate positioning component, for realizing the upper pipe end segment positioning component of pipe end segment location, being used for realizing seat cushion Lock support location cushion lock support positioning component, for realize seat cushion after-poppet location seat cushion after-poppet positioning component and use In the tail-hood support positioning component realizing tail-hood support location.
So, this weld jig structure is capable of knight's car sample vehicle frame rear section main body and each attached structure on it Location and installation between part, can conveniently use welding gun to quickly complete being welded and fixed between each component successively behind location.Make Each component relative-position error is reliable and welding operation is convenient and swift, provides cost savings.
